Takata Modifies Air-Bag Propellant Formula

Air-Bag Maker Adjusts Chemical Formula of Propellants Inside the Bags

TOKYO—Takata Corp. has adjusted the chemical formula of a propellant and revised the production process used to make its air bags, some of which have been recalled for exploding too forcefully and injuring drivers.

The modifications aren’t a response to any design flaws in previous air bags nor are they a direct consequence of recalls, a spokeswoman for the company said, describing them as routine improvements.
